Room temperature carbon nanotube based sensor for carbon monoxide detection

Room temperature carbon nanotube based sensor for carbon monoxide detection

Sulfonated single-walled carbon nanotubes have been used in an integrated electrode structure for the detection of carbon monoxide. The sensor responds to 0.5 ppm of CO in air at room temperature. All eight sensors with this material in a 32-sensor array showed good repeatability and reproducibility...
